While evaluating a receiver design, a K2 Narrow Spaced Dynamic Range measurement was performed to validate the test bench. The K2 plot is on the page: https://www.kn5l.net/newReceiverProject/plot-IMD/
If the two line equations are used, the Noise floor is -138 dBm and 2kHz dynamic range is 87 dB. These are close to the Sherwood values of -136 and 80. The K2 settings are my normal operation IF/AF BW settings, which is a little narrower than the Sherwood measurement parameters. The question is the low level IMD measurement points do not follow the line equation. Is this expected?
